' MOTION-PICTURE \AND TARGET APPARATUS.

Application filed May 20, 1919, Serial No. 298,406; Renewed December 1,1920, Serial No. 427,857. Original No. 1,889,877, dated September 6,1921. Application for reissue filed May 28, 1927. Serial My inventionrelates to improvements in motion picture machines, and also to motionpictureftarget apparatus of the class employinga target, a picture proccting device, and electrical connections between the target and theprojector actuated by the impact of a bullet on projectile on the targetfor automatically stopping the movement of the'picture film. d

In the employment of motion picture machines it is desirable at times topresent a still picture on the screen insteadof a moving picture, thus,for example, where the moving picture is being utilized 1n connectionwith a lecture or a talk,-or, more fre' quently, when the motion picturemachine is employed in connection wlth a target apparatus wherein theprojectingdevice is flopped by means actuated by the impact z' of'abullet orby firing a shot, etc;

Prior tomy invention, the stoppage of the picture 61m in order toproduce the still picturehas beenaccomplis'hed by stopping all ofthemoving parts of the machine, the

result. being that the machine-soon becomes destroyed or inefficient,due to the sudden.

4 stoppage of its rapidly moving parts.

An object of the present invention is to provide simple and etlicientmeans for stopping the movement of a picture film for the purposes abovedescribed, without affecting or stopping the rapidly moving parts of themachine.

A further object of my invention 15 to provide a new ,and improvedmotion picture target apparatus.

The moving picture machine, as illus- Referring to the drawings, Adesignates a trated, includes a casing 1, of any suitable construction,the lens 2, and a shutter 3. As shown, the movable parts are driven bymeans of an electric motor 4, although the machine may be operatedmanually. main drive shaft 5 is connected with the motor by means ofabelt 6 and drive wheel 7. 8 designates a fly wheel mounted on shaft 5.The film tape 9 is designed to be fed down through the machine from reel10, over opening 11 of frame 12, in the usual manner. w

The film passes over and is fed through the machine by the feed wheels.or sprockets 13 mounted on a shaft 14, and' the usual in' termitten-tlydriven wheels or' sprockets 15, the latter being mounted on shaft 16.Shaft 14 is driven from the main drive shaft 5 throughgearing' 17 and18, and the shaft 16 is also driven from shaft 5. The means illustratedfor driving the intermittently driven shaft 16 include a star wheel 19,of the Geneva type, mounted on and keyed to the shaft 16, a shiftablesleeve element 20 carrying a pin 21 and' having a clearancev space 22for the star wheel and a groove 23,

said element 20 being mounted and slidable on drive shaft 5. The shutter3, as illustrated, is driven from shaft 5 by means of gearing 24.

The elements above described, with the exception of the shiftable sleeveelement 20, are of known construction and are arranged to operate amotion picture machine in the usual manner. It should also be understoodthat my invention'is not limited to the combination of these elementswith means for arresting themovement of the film without The- * stoppingthe motor and the rapidlydmov mg parts of'the machine, for my inventionI may be embodied in motion picture machines from. that shown.

having mechanism difi'ering considerably A characteristic and importantfeature of my invention is the provision-f means cooperating with theintermittently driven film feed wheel or sprocket,- or said wheel orsprocket and the other film feed wheel or sprocket of a moton picturemachine, whereby the'movement of the filmthrough the machine may bestopped for a desired riod' of time without stopping or afi'ect- 1n theother movable parts of the machine. e mechanismemployed for sto pingtherotation of the intermittently (ii-wen shaft 16, orthe feed wheels orsprockets 13, in addition to the element 20, includes a movable bentdownwardly extending arm 25, pivotally secured ltO the framework of themachine with its fulci um point at 26.

nates a stop Arm carries a pin 27, the latter being enteredin the groove23 of element 20. The

lower portion of the arm is bent, as shownat 28, and said portion 28 isformed with a flangev or bent up portion 29. 30 desigelement-mounted onshaft 5, the function of which is 'to'prevent an inward movementjof arm25, and the 'consequent shifting of element 20 until the desiredinstant. That is to say, the .element 20- should be permitted to shdeonly when a complete picture is shown on the screen. Said'stop element30 is formed with a collar 31 having a' laterally extending slot 32throughwhich the flange 29' of arm' 25 may pass to permit the inwardmovement of said arm and element 20. The movement of arm ,25- iseifected by a horizontally extending having .one end attached to arm 25i at 34 and its opposite end connected with a clutch, and a link 35, thelatter being'pivotally secured to a portion of the frame.

As 'llustrated and as preferred, the move ment of the rod 33 is efiectedby means of a bar 36 connected with and ada ted .to be moved by the core37 of a solenoid 38 and .for this purpose, 'bar 36 is provided with a in39 entered in the pivotally mounted .lin

means. i

For the purpose ofstopping' the rotation of the feed sprockets 13 onshaft 14, when desired, I provide a.clutch mechanism'40.

Said clutch mechanism, as shown, is operated by. means of. the bar- 36,a pivotallysupported link 41 secured at 42 to the frame, a rod 43extending from the link to the pin 4-4 on bar 36 cooperating with thelink.

The parts just described are articularly illustrated in the detail viewof ig. 3, and,

35. It is evident, however, thatfbar 36 may be moved by otherthanelectrical as there shown, are arranged to drive the film feed wheels.An upward movement of the bar 36 will release the clutch mechanism andalso shift the slidableelement 20, thereby throwing pin-21 free of thestar wheel 19 as the formerrevolves with the element 20. A movement ofthe bar 36 in the opposite-direction or into the position shown by Fig.3 will permit the film to be fed through the machine, with the usualinterm ittent movement.

The mechanism herein described provides simple and eflicientmeans forautomatically stopping for a predetermined period .the movement of thefilm, thereby enabling a still picture to be shown on the screen, this abeing accomplished, without stopping the other movable parts of themotion picture machine. 1 1

In the present invention I have shown the motionpicture machine and theabove described means for stopping the picture film in connection with atarget apparatus and electrically operated means between the target andthe machine dcsignedto be oper ated by the impact of ,a bullet orprojectile on the. target.

Tl ic ta'rget structure 45 is similar to the target structure shown in apatent issued to ie-November 27, I923. No. 1,475,493. As-

' Bars also carry a vertical'row of plates 51 having divided endsadapted to straddle a vertically movable switch actuating rod- 52. Rod52 is provided'with a series of ins .53 which engage the divided ends ofp ates 51.

It will be understood that an inward movement of an impact .plate' will'tilt a bar 50, and that, when this occurs, the switch actuating rod 52will be raised. Raising the rod'is designed to complete an electriccircuit for the purpose of effecting certain operations hereinafterdescribed.

In the-embodiment of rn'y'invention as shownby the drawings, rentemployed inconnection withthe various parts of the apparatusis obtainedfrom the main line 60. i .t

An upward movement of the switch acbullet against one of the'plat-es 46,acting the electrical cur-' through the-means above-described, will op-Toggle arm 61 the upward movement of said rod, arm 63 crate a toggle arm'61 pivotally secured to an arm 62 of the frame. engages the lower endof rod 52, and, upon 7 of toggle 61 is moved to make contact with 12otuating rod 52 caused by the impact of 'a to move from stop 68, therebycomp e an enlarged portioni'ti disposed at the lower end of a pivotallymounted curved arm-65.

Arm is fulcrumedint'fidland has its cup-H per end attached to a slottedand horizontally. extending-arm 67.- v a The elements just describedconstitute a portion of an electrical switch device and timingapparatus, said switch and timing apparatus forming the subject ofUnited States Letters-Patent No. 1,503,834, issued to me August 5, 1924.f V

As'shown herein, 68 designates a fixed contact strip of the switchmechanism and 70 a move le switch arm. des' ned to be thrown by themovement of the orizontally movablearm 67. The connection between thearm 67 and the switch. arm 70 includes a pivotally mounted arm 71securedat 72 to the frame of the machine and pivotally' connected witharm 67 by a pin 73. Arm 71 at its upper end is provided with a pin 74adapted to operate in a slot 75 of the switch arm 70. 'As shown, amovementof bar 67 to the left' will cause switch arm-70 ting an electriccircuit to solenoid 38 of the motion picture machine, and at the sametime completing an electric circuit to a motor 76 of the timingmechanism.

The timing mechanism includes. in addition to the motor, motor shaft 77,having a worm 78 thereon, a pinion wheel 7 9 meshing with said ,worm, astriking pin 80 carried on the pinion, a pivoted arm 81 having its endsdivided and engaging a pin passed through arm 67, and a pivotallymountcd 1 arm 82 secured to the divided arm 81.

It will be understood that the closing of the circuit leading tosolenoid 38 enerf gizesthc core 37 of the said solenoid to raise Q thebar 36, thereby throwing out the clutch mechanism 40 an moving theslidableelement 20 on drive shaft 5 to disconnect said element fromtheflstar wheel carried on the intermittently drivenshaft 16, thusstopping the film feed wheels 13 and 15, The time the movement of thefilm is arrested depends upon the speed of rotation of the wheel 79; Itwill be understood that, with the closing of the circuit 90 to thesolenoid 3 8, a circuit pin 80 to make a revolution, for it will benoted that, upon each revolution of striking pin 80, said pin will comeinto contact with red 82, thereby causing the switch arm 70 to bebrought from engagement with contact block 69 to contact point The speedof the mot-or is controlled by point 68 into engagement with stop block69. V Forthe purpose of moving the screen or cuttainB, I provide asolenoid 93, the core '94 of which is employed for'movin'g a dog on aratchet wheel 96-mou-nted on the shaft of the screen reel. The circuit97 for solenoid 93 is also made and bro ken by means of the striking pin80 on pinion 79.

'This is effected by employing apivotaliy mounted switch arin 98 adaptedto be moved into contactflwith contact plate 99. y

100 designatesa movable shutter, preferably made o'fcolored mica,-thisshutter being adapted "to be moved over and away from the opening 11(see Fig. 1) by the movement of the 36 and the connections between saidbar andshut-ter. Said connections includea toggle a'rm 101 carrying a in102, a. pivotally mounted plate 103, the atter having a slotted portion104 into which the pin 102 is'entered. The function of the shutter 100is to change the color of v the picture thrown onto the screen duringthe time the movement of the film is arrested. It will be understoodthat the shutter maybe omittedif desired, although I,

,find it of advantage for the purpose of enn-g.-
